Feedback Wii Friend Number Addition

I was thinking more could be done to the Wii friend thing on the forums, such as when you click it, it brings up an e-mail to the Wii e-mail service, for example, if someone's Wii friend number is 1234-5678-1234-5678, then their e-mail would be w1234567812345678@wii.com, so just an idea if you can find someway to implement it
